Special Issue Information

Dear Colleagues,

Motion sickness is a sensory syndrome or disorder that has been widely known since ancient times with the advent of non-pedestrian transportation. It is recognized and diagnosed according to criteria recently stated by the Barany Society and can group together different entities: motion sickness, visually induced motion sickness and the resulting disembarkation sickness. The current pathophysiological mechanisms remain poorly understood, and it is clear that the networks underlying motion sickness remain a grey area to be explored with new means of investigation in neuroscience mainly the vestibular system and emotional related system/network. Although it is well known to the general public, there is a poor relationship between sensory neuroscience and clinical practice. At the interface between the sensory (visual, auditory, vestibular and somesthesic), emotional and hypothalamo-vegetative components, motion sickness indicates a functional disorder in the integration and/or abnormal interpretation of an “artificial” motion or a dynamic environment.

The digital and robotic technological development of autonomous cars, immersive simulators for professional training (civil and military), gaming, or the future metaverse network using virtual reality make motion sickness a physiological lock that should serve as a scientific, economic and industrial lever to develop large-scale research projects, both fundamental and applied, and effective countermeasures.

This Special Issue aims to review the physiopathology of motion sickness, the emotional aspects, the most recent advances in rehabilitation concepts, and perspectives on the next generation of means of transportation and of virtual reality and simulator systems.

Virtual reality (VR) technology provides highly immersive depth perception experiences; nevertheless, stereoscopic visual fatigue (SVF) has become an important factor currently hindering the development of VR applications. However, there is scant research on the underlying neural mechanism of SVF, especially those induced by VR displays, which need further research. In this paper, a Go/NoGo paradigm based on disparity variations is proposed to induce SVF associated with depth perception, and the underlying neural mechanism of SVF in a VR environment was investigated. The effects of disparity variations as well as SVF on the temporal characteristics of visual evoked potentials (VEPs) were explored. Point-by-point permutation statistical with repeated measures ANOVA results revealed that the amplitudes and latencies of the posterior VEP component P2 were modulated by disparities, and posterior P2 amplitudes were modulated differently by SVF in different depth perception situations. Cortical source localization analysis was performed to explore the original cortex areas related to certain fatigue levels and disparities, and the results showed that posterior P2 generated from the precuneus could represent depth perception in binocular vision, and therefore could be performed to distinguish SVF induced by disparity variations. Our findings could help to extend an understanding of the neural mechanisms underlying depth perception and SVF as well as providing beneficial information for improving the visual experience in VR applications.
